How do describe what it means to be an iPad? This is something that Apple cares about. If you have an iPad that is fundamentally different [more or device] then it's not really an iPad anymore.
Do they actually care? This sort of discrepancy has never bothered them before.
(see how the "Air" used to mean "ultra-premium thin and light", but now the iPad Air is heavier than the Pro, and the MacBook Air is just a brand they slap on the entry level MacBook, a model so entry level it's now sold at WalMart -- and the 15' Air is only 90 grams weight difference than the 14' Pro)
(see the "Apple Pencil" and how it means like 4 different things, with 4 different feature sets, and needs a product matrix spreadsheet to know which Pencil is safe to use with any given iPad)
See how "Apple TV" is both a hardware product (Apple TV 4K) and a service (Apple TV subscription) and an App (the Apple TV app, available on iOS, but also Roku and others), and a platform (the "Apple TV platform", where you can load other streaming services like Disney+ or Hulu or Paramount, into the Apple TV platform, which lives inside the Apple TV app, on your Apple TV device).
